Just got back, Let me know if you have any questions. Mex 1 is similar in size and condition to a county two lane up here. It can be ridden one direction in two hard days. I would recomend three if you want to soak up any scenery. The upper third of the pennisula is more populated and slower going.
The road is much more oily and greasy than we are used to. In general the vehicles large and small are in pretty poor conditon and leak like a colander. Especially on long climbs where the trucks are slow and working hard to pull the hill. I had a LOT of oil and grease all over the under side and checked air pressure a couple times before I was convinced that the loose feeling was road surface and not my tires.
